Struct holochain_core_types::error::CoreError

pub struct CoreError {
    pub kind: HolochainError,
    pub file: String,
    pub line: String,
}

Holochain Core Error struct Any Error in Core should be wrapped in a CoreError so it can be passed to the Zome and back to the Holochain Instance via wasm memory. Follows the Error + ErrorKind pattern Holds extra debugging info for indicating where in code ther error occured.

Fields

kind: HolochainError

file: String

line: String

Implementations

impl CoreError

pub fn new(hc_err: HolochainError) -> Self

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CoreError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CoreError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for CoreError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Eq for CoreError

impl Error for CoreError

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }
